how to write Console output to a log file

[altemir@es.ibm.com (Sebastia Altemir)]

If, under SuSE 8.2, I put this line
  echo "*** Running /ETC/INIT.D/NETWORK ***"
in "/etc/init.d/network", I can find this line in /var/log/boot.msg

Under Debian, - kernel 2.4.20 -, I place a similar ECHO line in
"/etc/init.d/networking", can see (very fast) on the console screen,
but can't find it in any file at /var/log.

What must I do to have it logged ? (boot.msg does not exist)

Thanks. Sebastian.
